Kylie Jenner welcomes her first child, a girl

Kylie Jenner gave birth to her first child, a girl, with boyfriend Travis Scott, the reality TV star and Kylie Cosmetics founder announced Sunday.

The baby, whose name has not been revealed, weighed 8 lbs., 9 oz., and was born Thursday. Jenner, 20, kept her pregnancy under wraps, and in a message to fans, she apologized for "keeping you in the dark through all the assumptions." The pregnancy "was one I chose not to do in front of the world," she said. "I knew for myself I needed to prepare for this role of a lifetime in the most positive, stress-free, and healthy way I knew how."

Jenner also released a video showing milestones from her pregnancy, as well as messages from family and friends and scenes from the delivery room. Jenner's sister Kim Kardashian West welcomed her third child, daughter Chicago, last month, and her sister Khloe Kardashian is expecting her first child this spring. Catherine Garcia
